pub trait FrameBuffer: Send + Sync {
    fn linesize(&self, idx: usize) -> Result<usize, FrameError>;
    fn count(&self) -> usize;

}

A series of methods to interact with the planes of frame.

Required Methods

fn linesize(&self, idx: usize) -> Result<usize, FrameError>

Returns the linesize (stride) of the idx-th frame plane.

fn count(&self) -> usize

Counts the number of frame planes.

fn as_slice_inner(&self, idx: usize) -> Result<&[u8], FrameError>

Returns an immutable buffer with the data associated to the idx-th frame plane.

fn as_mut_slice_inner(&mut self, idx: usize) -> Result<&mut [u8], FrameError>

Returns a mutable buffer with the data associated to the idx-th frame plane.
